WebLike Tom just said, you can truncate SHA-256 output to 128 bits for integrity, because 128 bits is enough to reasonably avoid collisions. However, hash functions like SHA-256 are not suited for key generation or file authenticity (only integrity). If you want to generate a key, use something like PKBDF2 or scrypt. WebFeb 9, 2024 · Byte Data: The AES encryption algorithm does operations on byte data instead of bit data. So it treats the 128-bit block size as 16 bytes during the encryption procedure. Key Length: The number of rounds to be carried out depends on the length of the key being used to encrypt data. The 128-bit key size has ten rounds, the 192-bit key size …

WebSuppose a computer using fully associative cache has 2 24 bytes of byte-addressable main memory and a cache of 128 blocks, where each cache block contains 64 bytes. a) How many blocks of main memory are there? b) What is the format of a memory address as seen by the cache; that is, what are the sizes of the tag and offset fields? WebA byte is a grouping of eight bits. Byte-addressable means that the computer stores data in bytes instead of single bits for example.
